get_included_files

(PHP 4, PHP 5, PHP 7, PHP 8)

get_included_filesinclude または require で読み込まれたファイルの名前を配列として返す

説明

get_included_files(): array

この関数は、 includeinclude_oncerequire あるいは require_once によりスクリプトにロードされたすべてのファイルの名前を取得します。

パラメータ

この関数にはパラメータはありません。

戻り値

すべてのファイル名を含む配列を返します。

最初にコールされたスクリプトは "include されたファイル" という扱いに なります。そのため、 include やその仲間たちにより 読み込まれたファイルの一覧に含めて表示されます。

複数回読み込まれているファイルも、 返される配列には一度しかあらわれません。

例1 get_included_files() の例

<?php
// このファイルは abc.php です

include 'test1.php';
include_once
'test2.php';
require
'test3.php';
require_once
'test4.php';

$included_files = get_included_files();

foreach (
$included_files as $filename) {
echo
"$filename\n";
}

?>

上の例の出力は以下となります。

/path/to/abc.php
/path/to/test1.php
/path/to/test2.php
/path/to/test3.php
/path/to/test4.php

As of PHP5, this function seems to return an array with the first index being the script all subsequent scripts are included to.
If index.php includes b.php and c.php and calls get_included_files(), the returned array looks as follows:

index.php
a.php
b.php

while in PHP<5 the array would be:

a.php
b.php

If you want to know which is the script that is including current script you can use $_SERVER['SCRIPT_FILENAME'] or any other similar server global.

If you also want to ensure current script is being included and not run independently you should evaluate following expression:

__FILE__ != $_SERVER['SCRIPT_FILENAME']

If this expression returns TRUE, current script is being included or required.

If you have a MAIN php script which you don't want to be included by other scripts, you could use this function. For example:

main.php:
<?php
function blockit()
{
$buf = get_included_files();
return
$buf[0] != __FILE__;
}

blockit() and exit("You can not include a MAIN file as a part of your script.");

print
"OK";
?>

So other script couldn't include main.php to modify its internal global vars.

It's perhaps not clear from the existing docs that the returned list contains nested include files as well.

That is, if A.php includes B.php, and B.php includes C.php, the result returned when calling get_included_files() from inside A.php WILL contain 'C.php'.

As is often the case, YMMV. I tried the __FILE__ and SCRIPT_FILENAME comparison and found this:

SCRIPT_FILENAME: /var/www/cgi-bin/php441
__FILE__: /raid/home/natpresch/natpresch/RAY_included.php

As an alternative:

count(get_included_files());

Gives one when the script is standalone and always more than one when the script is included.

This function aims to perform filtering of files that have been included :

<?php
function setIncludeFiles($arrayInc = array()){
$incFiles = get_included_files();
if((
count($arrayInc)>0)&&(count($incFiles)>0)){
$aInt = array_intersect($arrayInc,$incFiles);
if(
count($aInt)>0){
return
false;
}elseif(
count($aInt)<1) {
foreach(
$arrayInc as $inc){
if(
is_file($inc))
include(
$inc);
else{
return
false;
}
}
}
}else{
return
false;
}
}
?>

Usage :

<?php
$toBeInclude
= array('/data/your_include_files_1.php',
'/data/your_include_files_2.php',
'/data/your_include_files_3.php',
);
setIncludeFiles($toBeInclude);
?>

Return false if something goes wrong.

This is a great way to emulate Python's '__name__ = "__main__"'

<?php
if(get_included_files()[0] === __FILE__) doStuff();
?>
